AI Technical Summary

Benefits of technology

The present invention provides an information processing apparatus, method, and program that enhance the ease of use of display devices by preventing accidental settings from affecting the user experience. This is achieved by detecting and responding to control actions made by the user, such as adjusting settings or selecting options, to ensure that the device functions within the intended parameters and provides a seamless user experience. Additionally, the invention includes a threshold value to prevent accidental changes in settings, which otherwise could occur when the user reaches the control detection block beyond a certain distance from the display device. Overall, the invention improves the usability of display devices by making them more intuitive and user-friendly.

Problems solved by technology

The above-mentioned display device presents a problem that, the processing may be executed on the basis of settings not intended by the user, thereby lowering the ease of use of the display device because the user can grasp the distance between the user and the display device only approximately, especially in executing processing by setting different values in accordance with distances from the user to the display device.

first embodiment

1. First Embodiment

1-1. Exemplary External Configuration of Television Receiver

[0030]As shown in FIG. 1, a television receiver 1 as an information processing apparatus associated with an embodiment of the present invention has a display 2 based on an LCD (Liquid Crystal Display), an organic EL (Electro-Luminescence), or the like, and a loudspeaker 3 lower of the display 2.

[0031]In addition, the television receiver 1 has a stereo camera 4 composed of cameras 4A and 4B upper of the display 2. The stereo camera 4 takes an image of a space in front of the display 2.

1-2. Circuit Configuration of Television Receiver

[0032]As shown in FIG. 2, with the television receiver 1, a CPU (Central Processing Unit) 11 reads a basic program stored in a nonvolatile memory 12 and extends this basic program into a RAM (Random Access Memory) 13. This allows the CPU 11 to overall control the entire television receiver 1 via a bus 20 as instructed by the basic program.

[0033]Also, the CPU 11 reads various ap...

second embodiment

2. Second Embodiment

2-1. Configuration of Television Receiver

[0119]In the second embodiment of the present invention, unlike the first embodiment, a shape of the user's hand is recognized rather than detecting an input point from video data taken by the stereo camera 4. It should be noted that a configuration of a television receiver 1 is substantially the same as the configuration of the first embodiment, so that the description of the second embodiment is skipped.

[0120]To be more specific, the CPU 11 gets the video data taken by the cameras 4A and 4B of the stereo camera 4 as time passes and at every predetermined timing and then executes flesh color extraction processing on the video data taken by the camera 4A for example.

[0121]The CPU 11 detects a flesh color part obtained by the flesh color extraction processing as an input part and, at the same time, detects a position on a plane parallel to a display 2 of this input part and a distance from the stereo camera 4 as a three-dim...

embodiment 1

3-1. Other Embodiment 1

[0195]It should be noted that, in the first and second embodiments of the present invention described above, a three-dimensional position of the user's hand is detected from video data taken by the stereo camera 4.

[0196]However, the embodiments of the present invention are not limited to the above-mentioned configuration. For example, a three-dimensional position of the user's hand may be detected by use of proximity sensors of inductive type, electrostatic capacitance type, ultrasonic type, electromagnetic wave type, infrared ray type, and so on.

Abstract

An information processing apparatus include: a control detection block configured to detect a control in a predetermined detection space; a position detection block configured to detect a three-dimensional position of a control detected by the control detection block; a threshold value setting block configured, if the control has approached the control detection block beyond a threshold value set to a predetermined distance through the control detection block on the basis of a three-dimensional position detected by the position detection block, to set the threshold value farther from the control detection block than the predetermined distance; a setting change block configured, if the control has exceeded the threshold value set by the threshold value setting block, to change setting values for predetermined processing; and a processing execution block configured to execute the processing by use of the setting values set by the setting change block.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an information processing apparatus, an information processing method, and an information processing program and is suitably applicable to television receivers for example.[0003]2. Description of the Related Art[0004]Related-art television receivers are configured to receive signals specified by user operations done through a remote controller to execute processing corresponding to the received signals.[0005]However, these television receivers require users to do complicated operations, such as finding necessary operator buttons from among many operator buttons arranged on a remote controller.[0006]In order to overcome the above-mentioned problem, technologies are proposed, in which a display device arranged on a television receiver has a camera on the front side of the display device to take an image of three-dimensional movements of user's hand, for example, thereby executing the proce...
